What would grow well with a holly hedge
i am looking for ideas to buy a fast growing plant to thicken and add some interest to my rather thin but tall and established holly hedge. It extends around a sunny south facing to a shaded side return so the complementing plant would need to be able to cope with these different conditions. It has gOod drainage and quite sandy river basin soil. I've thought of a honeysuckle but not sure if that would work and if it does the. what type is recommended? Any ideas welcome please?
